Answer:

98 grams

Step-by-step explanation:

The simplest way to think about this is that the half life has elapsed 3 times, so you need to take the initial mass and divide it by 2 3 times, so 784/2/2/2 or 784/8 which is 98

Answer:

See my explanation below.

Step-by-step explanation:

Let's start with two random mixed numbers.

[tex]4\frac{3}{5}[/tex] ÷ [tex]5\frac{1}{4}[/tex]

The first step is starting with [tex]4\frac{3}{5}[/tex]. Think about going from the denominator to the number on the left. After you remember that rule multiply 4 by 5. You should get 20. After that, you add by the numerator. 20 + 3=23

This is how it would be written.

[tex]\frac{23}{5}[/tex]

Do the same for the next mixed number. 5 x 4 = 20 and add by the numerator 21.

[tex]\frac{21}{4}[/tex]

After this is done. You will multiply by those fractions. [tex]\frac{23}{5}[/tex] x [tex]\frac{21}{4}[/tex] = [tex]\frac{483}{20}[/tex] we would write it as [tex]24\frac{3}{20}[/tex] as a mixed fraction.

Answer:

The value of a is 4 ⇒ D

Step-by-step explanation:

In the system of equations

∵ y = ax ⇒ (1)

∵ ax + y = 16 ⇒ (2)

∵ The solution of the system is (2, 8)

∴ x = 2 and y = 8

→ To find the value of a substitute x by 2 and y by 8 in equation (1) or (2)

∵ y = ax

∵ y = 8 and x = 2

∴ 8 = a(2)

∴ 8 = 2a

→ Divide both sides by 2

∵ [tex]\frac{8}{2}[/tex] = [tex]\frac{2a}{2}[/tex]

∴ 4 = a

∴ The value of a is 4

Answer:

yes,Noah did bring enough money for the ticket.

Step-by-step explanation:

you know that it's going to 8 students and in total it's 100.You need to know how much each will need to pay so you divide 100 divided by 8.The quotient/answer to what each student will pay is 12.5. 13 dollars is more than enough to pay for the ticket so Noah did bring enough.

Answer:

the graph of w passe through point (8,-6)

Step-by-step explanation:

When you draw a line through points (-5, 7) and (3, -1) points (8,-6) also meets the line segment at the very bottom.

Answer:

The graph of w passes through (8,-6)  (FIRST ANSWER)

Step-by-step explanation:

The equation of the graph is -1x+2, therefore no other answer works

The slope is -1, not 2

The Y-intercept is (0,2), NOT the X-intercept

The zero is 2, not -1

Therefore, the only correct answer is The graph of w passes through (8,-6)

your answer luv- y-1/2x-7

Answer:

-3

Step-by-step explanation:

Simplifying

2x + 6 + -10x = 30

Reorder the terms:

6 + 2x + -10x = 30

Combine like terms: 2x + -10x = -8x

6 + -8x = 30

Solving

6 + -8x = 30

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6' to each side of the equation.

6 + -6 + -8x = 30 + -6

Combine like terms: 6 + -6 = 0

0 + -8x = 30 + -6

-8x = 30 + -6

Combine like terms: 30 + -6 = 24

-8x = 24

Divide each side by '-8'.

x = -3

Simplifying

x = -3

Answer:

x=-3

Step-by-step explanation:

Write the equation.

2x+6-10x=30  Combine like terms.

-8x+6=30        Subtract 6 on both sides.

     -6  -6

-8x=24            Divide by -8 on both sides.

/-8  /-8

x=-3

The length of the scale model of the car is 120 cm

From the question, we have the following parameters that can be used in our computation:

Length of a car = 3.6 meters

We have the scale to be

Scale = 1 cm to 30 cm

This means that

Scale = 1 cm : 30 cm

using the above as a guide, we have the following:

Scale : 3.6 meters = 1 cm : 30 cm

So we have

Scale = 3.6 m * 1 cm/30 cm

Evaluate

Scale = 0.12 m

Convert to cm

Scale = 120 cm

Hence, the length of the scale model of the car is 120 cm

Answer:

x = -11

Step-by-step explanation:

9x+42=4x-13

(add 13 to both sides)

9x+55=4x

(subtract 9x from both sides)

55=-5x

(divide by -5)

-11 = x

You isolate the x term basically.

First you bring 4x from the right hand side to the left hand side and so the equation would be: 9x - 4x + 42 = -13

Then you bring 42 from the left hand side to the right hand side so the equation would look something like this: 9x - 4x = -13 - 42

Next subtract the x terms and the numbers on the right hand side too so you get: 5x = -55

Remove the coefficient from x and bring it to the right hand side with the operation as division. So you get: x = -55/5

Solve the division and you get: x = -11

Polynomial mixing with Modulus. First time to see this in my life.

So from the graph it must be even-degree polynomial. It must be 4-degree polynomial judging from the x-intercepts.

There's a fraction/decimal as roots so...  Just look from the graph.

When x = 6 or f(6), y = -2 as shown in the graph.

So f(6) = -2
